Skimping on sleep makes for more Aß in the brain

Mounting evidence suggests that the concentration of Aß rises in people’s cerebrospinal fluid if they don’t sleep enough. However, scientists are unsure why that is. Do people make more of the peptide, or do they degrade less of it? A pilot study led by Brendan Lucey and Randall Bateman at the Washington University School of Medicine, St. Louis, now implies that enhanced production is to blame. Read more.
